WINDING DEVICE

[Problem] To provide a winding device with high safety wherein an operation means is automatically switched to a position at which drawing out of a wire is prevented when the wire is drawn out. [Solution] Provided is a winding device that controls the rotational operation of a wheel (18), wherein a control mechanism (22) is provided with the following: an operation means (30) that switches between an engagement state of a first locking tooth (24a) that prevents rotation in a direction in which a wire (20) is drawn out and an engagement state of a second locking tooth (24b) that prevents rotation in a direction in which the wire (20) is wound; and a switching mechanism that, in the case that the engagement state of the second locking tooth (24b) is to be maintained, pushes the locking means back to a state in which the second locking tooth (24b) engages with the teeth parts (18c) after an operation for drawing out the wire (20), and that, in the case that the engagement state of the second locking tooth (24b) is not to be maintained, pushes the operation means (30) back to an operation position at which the engagement state of the first locking tooth (24a) is achieved, thereby shifting to a state in which the first locking tooth (24a) engages with the teeth parts (18c).
